I'm already doing that, adding the machine to each mission. ?? It looks like I can add it whole episodes(set of missions) at time. Adding one statement to a file to add to all missions at once. This is what I mean.
That's not possible, as far as I'm aware of. Not a huge drawback, though - using my method you'll ever need to change each .mission file only once ... each subsequent change in the "emp.machine"-file will automatically apply to every mission you added the
#include "emp.machine" to.
IMHO the best solution would be to create a new "globals.inc" file and add
#include "globals.inc" to every mission. In that globals.inc you can then include every script or file you'll ever want to apply to every mission ... like the emp torpedo machine, for example. So if you ever wanted to add a "super duper mega tazer" script, you'd only need to add that file (or script) to the globals.inc instead of every separate mission file.
